Here's an example:

I would like the note-spacing of the first bar combined with the
continuation line of the second (or maybe something in between). I do
not want the note spacing of the second measure.
Thanks!
First: With the new LilyPond 2.23.4 which should be released any day now
(if I'm not mistaken), it will be possible to do <_[-]> instead of
<[_-]>, i.e. put a bracket around the accidental specifically. For
accidental-only figures, this gives a much closer spacing which may be
closer to what you want:
\version "2.23.4"
<<
\new Staff { s1 }
\new FiguredBass \figuremode {
\set implicitBassFigures = #'(99)
\bassFigureExtendersOn
<_[-]>2 <_->
}

Now, if you actually want to change the starting position of the bass
figure extender line, I think the only "officially" supported property
is BassFigureContinuation.padding, overriding which unfortunately
shortens the continuation line on _both_ sides, which is not what you
want. There's probably a more intelligent solution, but the first thing
I could come up with was to partially re-implement the drawing routine
for the continuation line with configurable left- and right-shorten-lengths:
\version "2.22.1"
shortenContinuationLine =
#(define-music-function (left-shorten right-shorten) (real? real?)
#{
\override BassFigureContinuation.stencil =
#(lambda (grob)
(let*
((default (ly:figured-bass-continuation::print grob))
(thick (* (ly:output-def-lookup (ly:grob-layout grob)
'line-thickness)
(ly:grob-property grob 'thickness 1)))
(default-ext (ly:stencil-extent default X)))
(make-line-stencil
thick
(+ (car default-ext) left-shorten) 0
(- (cdr default-ext) right-shorten) 0)))
#})
\score {
\new Staff {
{
<<
{
f''8 e'' d'' c'' b'2 |
f''8 e'' d'' c'' b'2
}
\new FiguredBass {
\figuremode {
\bassFigureExtendersOn
<[_!]>8 \once \shortenContinuationLine 1 0 <_!> <_>8 q8 s2 |
<[_!]>8 <_!> s16 <_> q8
}
}
>>
}
}
}
